RooFING ELEMENT.

or MASSACHU- Application led October 2, 1924.v Serial No. 741,117.

This invention relates to improvements in method of producing roofing strips and roduct thereof, and specifically contemp ates cutting from a sheet of rooting material individual roofing strips without any waste of material, which, when laid on a roof, are self-spacing relative each other to present an attractive Yappearance and contrasting fields of light, dark and shaded intermediate areas. Y

Briefly, a continuous sheet of previously watei'proofed felt having a granular surfacing on one or both sides is fed to a roofing machine, .severed transversely entirely across its Width and simultaneously or subsubsequently having a plurality of sets of short opposed right angular incisions produced adjacent and relative to the severed edge. The spaces between these incisions are then folded over the body of the-strip, preferably upon the exposed granular face thereof. 'g

From the standpoint of economy of production, ease and certainty of accurate spacing on the roof, attractiveness of design and speed with which the shinglescan be laid on a roof, the product of this invention possesses many advantages.-

In the drawings: t

Fig. 1 is a plan View of an individual shingle strip severed from a sheet of rooting material, illustrating the manner of making the incisions.

Fig. 2 is a plan vievv7 of the stri-p, with *theA tab portions formed by the incisions folded back upon the face of the strip.

Fig. 3 is an edge view of the construction shownin Fig. 2. l

Fig. 4 is a viewA similar to Fig. 3, of a slightly modified form of construction.

Fig.'5 isa plan view of a pluralityof strips assembled on a roof.

Referring in details to thedrawings, 1 designates an individual shingle strip of rectangular shape cut from a continuous sheet of previously prepared rooting material, consisting of a felt base saturated with a Waterproofing compound and having 1mpose`d on one or bot-h surfaces a granular surface of any predetermined or contrasting colors, red, green, brown, etc. 1n 'the preferred form of construction, the exposed surface only has granular material imbedded therein, the

loiver/ sruface presenting the color of the waterproofing material.

Adjacent the line of transverse severance 2, asf-thefcontinuously advancing sheet is fed forward to be transversely severed entirely acrossthe width, are either simultaneously or subsequently produced a plurality of sets of. opposed perpendicular incisions 3 terminating preferably short of the central transverse cioss seotioiil of the sheet to produce the tabs 4. Preferably as part of the saine operation, these tabs 4 aie folded back upon thevexposed surface of the strip (Fig.v 2), the upper edge 5 terminating about midway transversely of the strip. The granular lmaterial is designated as 6 andV maybegreen, gray, red, brown, slate or'other desired color,

while the exposed'portion 7 of the folded tab ispreferably devoid of any granular surfacing and presents a darker color, for instance, black, Where asphalt is used as the" water- 75 The shinglesv when la'id'on a roofy (see Fig.

proofing medium.

5) present a roof having contrasting light, dark and-shaded areas. The vlower edges 2 of successive overlying shingles may abut directly up'on the butt edge 5, thus self-spacl ing individual shingles relative to each other. In the embodiment of my invention explained above, the entire area of the tab V4 may be attached to the body portion of the strip (Fig.

However, as shown in Fig.l4, theupperportion 8 of the tab may be left uiiattached, thus producing pockets 9 for the edges of overlying shingles. It will be seen that there will be no waste in cutting shingle strips in l accordance with this invention, from a continuous sheet of roofing material, while at the same time producing a self-spacing shingle strip.

I claim as my invention:

k1.*As a new article of manufacture, a s trip of roofing material substantially rectangular in shape, provided .with spaced rectangular notches extending inwardly from the lower edge and integrally connected overlying portions folded upon and attached to the upper surface ofthe strip, said integrally connectedportions comprising the material severed between individual sets of notches, a portion of the outer end of each overlying folded portion forming a shoulder with which the lower edge of an overlying strip is adapted to align and abut.

2. A new article of manufacture comprising a strip of flexible roofing material sub-y stantially rectangular in shape and having a granular surfacing on one. side, said strip being provided with spaced rectangularnotches extending inwardly from the lower edge and integrally connected Aoverlying portions folded upon and attached to the surface ofthe strip, said integrally con-- a granular surfacingon one side, said strip' being provided with spaced rectangular 'notches extending -inwardly from the lower edge and integrally connected overlying portions folded upon and attached to the surface of the strip, said integrally connected portions comprising the material severed between individual sets of notches, the exposed surface of the overlying folded portions resenting fields of different colors than the gody of the strip, a portion of the outer end of each overlying portion forming a shoulder with which the edge of an overlying strip is adapted to align and abut.

4. A new article of manufacture comprising a strip of iiexible roofing material substantially rectangular in shape and having a granular surfacing on one side, said s trip being provided with spaced rectangular notches extending inwardly from the lower edge and integrally connected overlying portions folded upon"and attached to the surface of the strip, said integrally connected portions comprising the material severed between individual sets of notches, the upper edges of the overlying folded portions foriuing shoulders against which the lower edges of overlying strips are adapted to abut and with which they automatically align.
